Subject: [PATCH v2] staging/wilc1000: fix wilc_mac_xmit()'s return type
Date: Thu, 26 Apr 2018 22:54:33 +0200	[thread overview]
Message-ID: <20180426205433.30308-1-luc.vanoostenryck@gmail.com> (raw)
In-Reply-To: <3c4bbd52-5af9-72b9-732b-f83f0bd23905@microchip.com>

The method ndo_start_xmit() is defined as returning an 'netdev_tx_t',
which is a typedef for an enum type, but the implementation in this
driver returns an 'int'.

Fix this by returning 'netdev_tx_t' in this driver too
and accordingly change 'return 0;' by 'return NETDEV_TX_OK;'
